The perspective projection is very familiar to us as human beings, because our eye produces such a perspective projection. An important attribute of the perspective projection, in contrast to the parallel projection, is that objects at a larger distance to the viewer or camera are displayed smaller.

WebThe perspective projection can be constructed with glm::perspective (fovy, aspect, near, far);. The first parameter gives the field of view angle. The angle is defined in radians if you have set #define GLM_FORCE_RADIANS. In our script, we have used a field of view angle of 45 degrees (pi/4 in radians).
